Unless otherwise noted, these free entrances apply to all federal public lands, including those associated with The Fish and Wildlife Service and National Wildlife Refuge System, The National Park Service, Bureau of Land Management and U.S. Forest Service, Bureau of Reclamation, the National Parks Promotion Council, and the National Parks Hospitality Association.

But wait, there’s more! Keep an eye out for special travel and activity discounts on Fee-Free Days. For example, the Swan Mountain Outfitters in Glacier National Park will offer horseback-riding package deals on June 9 and September 29.

Saving on admission is always a plus, but stretch that hard-earned dollar a little further with deals being offered in surrounding areas. Grab deals in select gateway communities around the national parks.

Park concessioners sometimes have special deals during free admission weekends, so be sure to check out Oh, Ranger! for more postings on how to save money. State park systems often offer free admission, so check with your local park system to find out when you can scoop the deals.
